Enclosed units

As long term contractors to Southern Rail/GTR, K H Engineering Services find themselves in frequent need to deal with protection of mains power equipment within areas of high DC power usage. This specialist protection is required for all electrical mains supplies likely to be used by the public – such as socket outlets, ticket machines, hand driers, water heaters and more recently electric vehicle charging points to BS 7671 in station car parks.

The problem of course is to eliminate nuisance tripping from induced currents which would activate a cut-off in normal equipment. Fortunately for K H Engineering Services, our FDB 11 from is a proven DC immune solution to this problem and on the DC approved list which makes it ideal for use on the Southern Line and other lines from North London to Kent and through to Portsmouth where they are recognised electrical maintainers.

Explained Qualifying Supervisor Tony Mace: “We have found the FDB 11 units excellent for all our installation work, whether it be renovation or new build. We have always found the sales team at FDB to be efficient, timely, very competitive and always helpful.”

“The FDB 11 has proven itself extremely reliable and flexible since we can readily obtain it in a range of standard ratings which suit our need for 16A or 32A current capacity with 30mA trip DC immune RCDs. When required we can also get them in multiple housings.”

Follow the KH Engineering example and contact us now to discuss your power protection needs.

Our FDB electrical protection family of RCD and RCBO devices runs from the Multiway FDB 2 modular panel through the FDB 11 at 230V for general purpose building renovation upgrade and maintenance projects and the FDB 13, FDB 15 and FDB 19 3 phase units for new build installations. Also in the family is the FDB 27 MOD spec unit for aircraft or army hangers new build and replacement installations.

These proven units are a convenient option for new or replacement installations offering long life and reliability – they are available from our Online store here.

Our FDB11 is a general purpose RCD panel unit providing overload and short circuit protection for industrial, academic, institutional and corporate applications. Installation is quick and easy with the FDB11 housed in a sheet metal enclosure.

Three enclosure sizes of FDB11 are available, 10 to 32 amp, 40 to 63 amp and 80 to 100 amp, conforming to BS4293 and BSEN60898.

In addition the FDB11 has been developed for specialist use to protect against induced DC current which can otherwise cause nuisance tripping in AC equipment adjacent to high voltage DC lines on railways. This is important in nearby offices, retail outlets and café/restaurants for example. The FDB11 is approved by Network Rail for these situations.

The use of RCD electrical technology has become commonplace in all areas of building services where the safety and convenience of this type of protection is of great value – but RCDs and their “sister” MCBs often need to be housed in specialist enclosures which provide for the integration of a number of devices in a custom system. Here at FDB Electrical we have created the FDB11 as a unit which installers can readily customise and which also provides for the use of multiple units in a grid layout. The facilities offered by the FDB11 are especially of value in the industrial and institutional arenas where capacities of 40A to 63A and up to 100A can be accomodated
